Thank you all for using my module! I know that it hasn’t been updated in a while as there has been no request for feature expansion apart from the TrackNo request seven months ago. The addition of that field was a bit of a hack on my part and it is not implemented in the best way, sorry for that.

As you have found out there is no additional filtering done apart from matching to and from destination ids. The reason for this is that, for most use cases, setting the destination id should be enough. Of course, if the destination id is just a waypoint, the ultimate destination might be different.

If you have request for new/changed functionality, do let me know.
